“…Anion recognition by artificial receptors has attracted considerable attention in the field of host-guest chemistry due to the important roles of anions in biomedicinal and chemical processes [1][2][3][4][5][6][7][8][9][10]. Artficial anion receptor has shown prospects of unique application in the synthesis of anion sensors [11,12], membrane transmit carriers [13,14] and mimic enzyme catalysts, etc.…”

“…According to this, we synthesized two novel receptors (Scheme 1), one containing phenolic hydroxyl group and diamide (1), the other containing only diamide (2), to examine the difference of anion binding ability based on the hydroxyl group and diamide recognition sites and explore the interaction mechanism. Results indicated receptor 1 showed high selectivity to acetate anion in DMSO and the mixture solution DMSO/H 2 O.…”

Two novel artificial receptors, one containing phenolic hydroxyl group and diamide (1), the other only containing diamide (2), were designed and synthesized. The binding ability evaluated by UV-vis and fluorescence titration experiments in dry DMSO revealed that compound 1 could selectively recognize AcO -. In particular, the binding ability can also be detected in the DMSO/H 2 O solution by UV-vis. The interference experiment result showed that the binding ability was not influenced by the existence of other anions. In contrast, there were no detectable interaction between receptor 2 and anions. The further insights to the nature of interaction between receptor 1 and AcO -were investigated by 1 H NMR titration experiments and theoretical investigation, which demonstrated receptor 1 complexed AcO -through the synergistic hydrogen bonding interaction of OH and NH.
